Element Log (Per Request By Twilight) - Entry 1
The Elements of Harmony: magical relics that have been used to stop many before, and more even now. Throughout all of history, there have been the six Elements: Honesty, Kindness, Generosity, Laughter, Loyalty, and Magic (which was not always known to be Magic, but was known to exist with the other Elements). Every book that has information on the Elements of Harmony and says how many there are, would say that there were six Elements. No more, no less.
In the one thousand years that Nightmare Moon was sealed in the moon by the Elements of Harmony, they were no used in any way, and were kept safely in the Castle of the Two Sisters. Before Nightmare Moon, there were other enemies that had the Elements used on them, though to find who specifically had the Elements used on them is rather difficult.
My friend (though technically she hadn't become my friend yet), Twilight Sparkle, had been looking into the Elements of Harmony to stop Nightmare Moon, and had found out (as said in essentially all sources on them) that there were six Elements, the final one being unknown. After finding the six Elements and standing up to Nightmare Moon, everything was just as said in the books relating to the Elements: there were six Elements, five being the ones that were know, and the sixth one being the Element of Magic.
However, Nightmare Moon had spoke of a seventh Element that was needed to complete the Elements of Harmony, which had never been heard of before. There had never been a seventh Element in all of Equestrian history, nor had anypony even heard of a seventh one. Though this may have seemed like Nightmare Moon was trying a last-ditch attempt to stop the Elements from stopping her (specifically the Nightmare that was corrupting Princess Luna was trying to stop the Elements).
Strangely enough, though, she was right, and there was a seventh Element of Harmony that was needed to activate all of the other ones! The six Elements of Harmony that the ponies were using had been unable to active, and Nightmare Moon had decided to attack using fragments of stone (from the Elements of Harmony, which she had broke, but there's no need for specifics) that she flung at the ponies with the six Elements of Harmony (to specify, those ponies also became my friends; I had interacted with all of them {except for Twilight Sparkle} many times, but my shyness over who I was kept me from growing close to them).
I had been following my friends (to specify, again, they were not my friends yet) into the Everfree (where they had been looking for the Elements) as to see what they had been up to, and I ended up witnessing the events I have written about. So when Nightmare Moon attacked (rather lazily and foolishly, I might add) I decided to block the hits so my friends (perhaps I shouldn't refer to them as my friends yet; as in at this part where this is being written) wouldn't get hurt. As a Changeling, I would have my chitin to absorb some of the blow, but when sharp stones are coming towards you, they're going to hurt no matter what.
However, the shards that had been thrown towards me instead began to circle me, in the same manner as the other shards had been circling the other ponies. The Elements of Harmony then "activated" and Nightmare Moon was cleansed and became Princess Luna again. It had turned out that I was the seventh Element of Harmony, but what I was the Element of was unknown.
After extensive research with my friend Twilight (with my other friends assisting at times), we have found nothing relating to a seventh Element existing, let alone knowing what it represented. So unfortunately, I do not believe that this log I have written will contain anything useful other than memories. However, maybe we will found out what my Element represents at some point.
Element Log - Entry 2
I felt like we were looking at this all wrong. Twilight kept (and keeps) having us look through books involving the six Elements of Harmony, luck, and the number seven, but are we just overthinking this? I decided to ask the others what they did to "earn" their Elements, so I can try and figure out what I did!

Element Log - Entry Three
Okay, so maybe the other entry wasn't very helpful. I know what the others did to show that they represented the Elements, but I still don't know what I did. The only time I even interacted with the others was at the end when I blocked Nightmare Moon's attack.
Wait a second...
I'll finish this entry later. Maybe Twilight has a Flashback Spell!

Thanks to that Flashback Spell, I finally have the answers I need!
